I/O PORTS (Cont’d)
10.7 DEVICE-SPECIFIC I/O PORT CONFIGURATION
The I/O port register configurations are summa-
rised as follows.
Standard Ports
PA7:0, PB6:0
PC1:0 (multiplexed with OSC1,OSC2)
The selection between OSC1 or PC0 and OSC2 or
PC1 is done by option byte. Refer to section 15.1
on page 145. Interrupt capability is not available
on PC1:0.
Note: PCOR not implemented but p-transistor al-
ways active in output mode (refer to Figure 31 on
Interrupt Ports
Ports where the external interrupt capability is
selected using the EISR register
Table 10. Port Configuration (Standard ports)
Note: On ports where the external interrupt capability is selected using the EISR register, the configura-
tion will be as follows:
